The invention particularly provides an internal trajectory low-speed friction force simulation test testbed. The problem that an existing ammunition friction force test is obtained through calculation, so that the test precision is low is solved. A sleeve-shaped simulation gun bore, a linear push rod motor and a hollow oil pressure ejector rod are arranged above a workbench, a linear bearing blockis arranged on the sleeve-shaped simulation gun bore, a support I is arranged on the linear push rod motor, a support II is arranged on the hollow oil pressure ejector rod, a push rod of the linear push rod motor is fixedly connected with the sleeve-shaped simulation gun bore, annular limiting blocks are arranged at the left end and the right end of the sleeve-shaped simulation gun bore, annularfelt pads are fixed to the inner sides of the two annular limiting blocks, a hollow test projectile is arranged in the sleeve-shaped simulation gun bore, the hollow oil pressure ejector rod communicates with the right end of t
